Xeris Biopharma Announces Results of the Extended Evaluation of Recorlev® (Levoketoconazole) From the Phase 3 Sonics Study Published in the European Journal of Endocrinology
First prospective long-term levoketoconazole study demonstrating a sustained effect on cortisol levels, as well as improvements in biomarkers of Cushing’s syndrome (CS) comorbidity, clinical signs and symptoms of CS and quality of life (QoL).
With a median treatment duration of 15 months, levoketoconazole was well tolerated and no new drug-related safety signals were observed.
Further supports a role for levoketoconazole in long-term therapy for patients with endogenous Cushing’s syndrome (CS).
Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a growth-oriented biopharmaceutical company committed to improving patients’ lives by developing and commercializing innovative products across a range of therapies, today announced that the European Journal of Endocrinology (EJE) published the extended evaluation (EE) results of the SONICS study (NCT01838551) evaluating longer-term effects of levoketoconazole on cortisol levels, biomarkers of Cushing’s syndrome (CS) comorbidities, clinical signs and symptoms of CS, and quality of life. 1 The manuscript also reports findings from pituitary adenoma imaging in the SONICS study.
For the first time, the longer-term effects of levoketoconazole are reported from the EE phase of the previously published SONICS study 1,2 . EE study participants (N=60) received maintenance treatment with levoketoconazole (median exposure for entire study of 15 months, range 7.9-22 months) with assessments scheduled at Month 9 and Month 12. The majority (39/60 [65%]) received levoketoconazole doses of 600 mg/day or less at the start of the EE period. Forty-six (77%) patients completed the study (Month 12).
Key Study Findings:
Sixty patients entered EE at Month 6; 61% (33/54 with data) exhibited normal mean urinary free cortisol (mUFC). At Months 9 and 12, respectively, 55% (27/49) and 41% (18/44) of patients with data had normal mUFC. In addition, reductions in late-night salivary cortisol (LNSC) and random serum cortisol were observed at Month 6, 9, and 12.
Mean fasting glucose, total and LDL-cholesterol, body weight, body mass index, abdominal girth, Cushing QoL, and BDI-II scores improved from study baseline at Months 9 and 12.
Female patients reported significant mean decreases in hirsutism score at all assessments; mean testosterone levels decreased significantly at Month 6 and were maintained throughout EE period
Of 31 patients with tumor measurements at baseline and Month 12 or follow-up, largest tumor diameter was stable in 27 (87%) patients, decreased in 1, and increased in 3 (largest increase 4 mm).
Forty-six patients completed Month 12; 4 (6.7%) discontinued during EE due to adverse events. The most common adverse events in EE were arthralgia, headache, hypokalemia, and QT prolongation (6.7% each)
No patient experienced ALT or AST >3x ULN, QTcF interval >460 msec, or adrenal insufficiency during EE.
"The results from this extended evaluation of the SONICS study provide important new evidence in support of Recorlev and will help inform clinicians’ decisions and individualization of medical therapy for patients with endogenous CS,” said Dr. Ken Johnson, Senior Vice President, Global Development and Medical Affairs at Xeris. "I would like to extend our gratitude to all the investigators, study coordinators and patients who participated in the SONICS trial program. Their contributions are integral in our mission to improve outcomes for patients with this rare, debilitating, and life-threatening condition.”
Recorlev received Food and Drug Administration marketing approval in December 2021. The initial approval was based upon safety and efficacy data from two positive Phase 3 studies that evaluated a combined study population of 166 patients, which was representative of the adult drug-treated U.S. population with Cushing’s syndrome. 2 The SONICS study met its primary and key secondary endpoints, significantly reducing and normalizing mean urinary free cortisol concentrations without a dose increase (detailed results here ). 2,3 LOGICS, a double-blind, placebo-controlled randomized-withdrawal study that met its primary and key secondary endpoints, confirmed the efficacy and safety of Recorlev in normalizing and maintaining therapeutic response compared with placebo (detailed results here ). 2
About Cushing’s syndrome
Endogenous Cushing’s syndrome is a rare, serious, and potentially fatal endocrine disease caused by chronic elevated cortisol exposure–often the result of a benign tumor of the pituitary gland. This benign tumor tells the body to overproduce high levels of cortisol for a sustained period of time, which often results in characteristic physical signs and symptoms that are distressing to patients. The disease is most common among adults between the ages of 30–50, and it affects women three times more often than men. Women with Cushing's syndrome may experience a variety of health issues including menstrual problems, difficulty becoming pregnant, excess male hormones (androgens), primarily testosterone, which can cause hirsutism (growth of coarse body hair in a male pattern), oily skin, and acne. 4
Additionally, the multisystem complications of the disease are potentially life threatening. These include metabolic changes such as high blood sugar or diabetes, high blood pressure, high cholesterol, fragility of various tissues including blood vessels, skin, muscle, and bone, and psychological disturbances such as depression, anxiety, and insomnia. 4 Untreated, the five-year survival rate is only approximately 50%. 5
About Recorlev®
Recorlev® (levoketoconazole) is a cortisol synthesis inhibitor for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not been curative. 2 Endogenous Cushing’s syndrome is a rare but serious and potentially lethal endocrine disease caused by chronic elevated cortisol exposure. 2 Recorlev is the pure 2S,4R enantiomer of ketoconazole, a steroidogenesis inhibitor. 2 Recorlev has demonstrated in two successful Phase 3 studies to significantly reduce mean urine free cortisol. 2
The Phase 3 program for Recorlev included SONICS and LOGICS, two multinational studies designed to evaluate the safety and efficacy of Recorlev when used to treat endogenous Cushing’s syndrome. The SONICS study met its primary and secondary endpoints, significantly reducing and normalizing mean urinary free cortisol concentrations without a dose increase. 2,3 The LOGICS study, which met its primary endpoint and key secondary endpoint, was a double-blind, placebo-controlled randomized-withdrawal study of Recorlev that was designed to supplement the efficacy and safety information provided by SONICS. 2 The ongoing open-label OPTICS study will gather further useful information related to the long-term use of Recorlev.
Recorlev received orphan drug designation from the FDA and the European Medicines Agency for the treatment of endogenous Cushing's syndrome.
Indication & Important Safety Information for Recorlev®
BOXED WARNING: HEPATOTOXICITY AND QT PROLONGATION
HEPATOTOXICITY
Cases of hepatotoxicity with fatal outcome or requiring liver transplantation have been reported with oral ketoconazole. Some patients had no obvious risk factors for liver disease. Recorlev is associated with serious hepatotoxicity. Evaluate liver enzymes prior to and during treatment.
QT PROLONGATION
Recorlev is associated with dose-related QT interval prolongation. QT interval prolongation may result in life-threatening ventricular dysrhythmias such as torsades de pointes. Perform ECG and correct hypokalemia and hypomagnesemia prior to and during treatment.
INDICATIONS AND USAGE
Recorlev is a cortisol synthesis inhibitor indicated for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not been curative.
Limitations of Use
Recorlev is not approved for the treatment of fungal infections.
CONTRAINDICATIONS
Cirrhosis, acute liver disease or poorly controlled chronic liver disease, baseline AST or ALT > 3 times the upper limit of normal, recurrent symptomatic cholelithiasis, a prior history of drug induced liver injury due to ketoconazole or any azole antifungal therapy that required discontinuation of treatment, or extensive metastatic liver disease.
Taking drugs that cause QT prolongation associated with ventricular arrythmias, including torsades de pointes.
Prolonged QTcF interval > 470 msec at baseline, history of torsades de pointes, ventricular tachycardia, ventricular fibrillation, or prolonged QT syndrome.
Hypersensitivity to levoketoconazole, ketoconazole or any excipient in Recorlev.
Taking certain drugs that are sensitive substrates of CYP3A4 or CYP3A4 and P-gp.
WARNINGS AND PRECAUTIONS
Hepatotoxicity
Serious hepatotoxicity has been reported in patients receiving Recorlev, irrespective of the dosages used or the treatment duration. Drug-induced liver injury (peak ALT or AST greater than 3 times upper limit of normal) occurred in 13% of patients using Recorlev. Avoid concomitant use of Recorlev with hepatotoxic drugs. Advise patient to avoid excessive alcohol consumption while on treatment with Recorlev. Routinely monitor liver enzymes and bilirubin during treatment.
QT Prolongation
Use Recorlev with caution in patients with other risk factors for QT prolongation, such as congestive heart failure, bradyarrythmias, and uncorrected electrolyte abnormalities, with more frequent ECG monitoring considered. Routinely monitor ECG and blood potassium and magnesium levels during treatment.
Hypocortisolism
Recorlev lowers cortisol levels and may lead to hypocortisolism with a potential for life-threatening adrenal insufficiency. Lowering of cortisol levels can cause nausea, vomiting, fatigue, abdominal pain, loss of appetite, and dizziness. Significant lowering of serum cortisol levels may result in adrenal insufficiency that can be manifested by hypotension, abnormal electrolyte levels, and hypoglycemia. Monitor 24-hour urine free cortisol, morning serum or plasma cortisol, and patient’s signs and symptoms for hypocortisolism during treatment.
Hypersensitivity Reactions
Hypersensitivity to Recorlev has been reported. Anaphylaxis and other hypersensitivity reactions including urticaria have been reported with oral ketoconazole.
Risks Related to Decreased Testosterone
Recorlev may lower serum testosterone in men and women. Potential clinical manifestations of decreased testosterone concentrations in men may include gynecomastia, impotence and oligospermia. Potential clinical manifestations of decreased testosterone concentrations in women include decreased libido and mood changes.
ADVERSE REACTIONS
Most common adverse reactions (incidence > 20%) are nausea/vomiting, hypokalemia, hemorrhage/contusion, systemic hypertension, headache, hepatic injury, abnormal uterine bleeding, erythema, fatigue, abdominal pain/dyspepsia, arthritis, upper respiratory infection, myalgia, arrhythmia, back pain, insomnia/sleep disturbances, and peripheral edema.
DRUG INTERACTIONS
Consult approved product labeling for drugs that are substrates of CYP3A4, P-gp, OCT2, and MATE prior to initiating Recorlev.
Sensitive CYP3A4 or CYP3A4 and P-gp Substrates : Concomitant use of Recorlev with these substrates is contraindicated or not recommended.
Atorvastatin : Use lowest atorvastatin dose possible and monitor for adverse reactions for dosages exceeding 20 mg daily.
Metformin : Monitor glycemia, kidney function, and vitamin B12 and adjust metformin dosage as needed.
Strong CYP3A4 Inhibitors or Inducers : Avoid use of these drugs 2 weeks before and during Recorlev treatment.
Gastric Acid Modulators : See Full Prescribing Information for recommendations regarding concomitant use with Recorlev.
USE IN SPECIFIC POPULATIONS
Lactation : Advise not to breastfeed during treatment and for one day after final dose.
